Identify gems

Hello everyone . I am new in the site. I’ll appreciate if you can help me identify some gems that we ( my siblings and myself) inherit from our grand father,

He was a jeweler in Argentina.
I have some general pictures, but if you would like a more detailed picture of any other of them, just let me know. I am planning a trip to USA by end of March. If you have any suggestion where I can take them for identification, that would be very helpful too. Regards.
